2 Claims. (Cl. 19-159) This application is a division of our prior application led June 8, 1948, Serial No. 31,714.

The invention relates to mechanism provided for continuously moving a sliver can during the operation of a drawing frame or other similar textile machine, and as the product of the machine is being coiled therein.

It is desirable that the sliver be deposited in the sliver can in superposed ybut circumferentially displaced coils, and it is also desirable that the sliver receive no twist from the motion of the can.

It is the general object of our invention to provide improved and very simple mechanism for producing a circular but non-rotational motion of a sliver can in a textile machine.

Our invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Preferred forms of the invention are shown in the drawings, in which Fig. 1 is a sectional side elevation showing portions of a coiling mechanism embodying our invention; and

Fig. 2 is a plan view of our improved can-rotat ing mechanism, with certain parts shown in section.

Referring particularly to Fig. 1, we have shown a sliver can C mounted upon a rotatable can support Illa and located under a coiler head l2 having an inclined delivery passage I3. The head I2 is mounted in a fixed frame or casing I4 and is provided with a ring gear I5 engaged by a gear I6 on a drive shaft I8. The shaft I8 may be continuously rotated from a power shaft 20 through bevel gears 2 l and 22.

The sliver is fed to the passage I3 through a trumpet 24 and between draft rolls 25, the rear roll only being shown in Fig. 1. The rolls 25 have gear connections to the' drive shaft I8 and are continuously rotated thereby.

The parts thus far described in themselves form no part of our present invention, which relates particularly to the mechanism for rotating the can support Illa and the can C in a circular path but without change of orientation.

The rotatable support Illa for the can C has a pivot stud 30 xed therein, which stud is received in an eccentric bearing opening 3| in the disc portion 32 of a worm gear 33. This gear 33 is continuously rotated about the point A (Fig. 2) by the drive shaft I8 through bevel gears 35 and 36, a. worm shaft 31 and a worm 38 engaging said -worm gear 33. The gear 33 is rotated on a stud 40 secured in a xed frame member 4I, and the support Illa and can C are moved bodily in a circular path B centered at the point A.

To maintain fixed orientation of the support Illa and can C, the fixed stud 40 is provided with 5l fixed thereto and of 2 a fixed sprocket 50. The pivot stud 30 of the rotatable support Illa is provided with a sprocket the same size and clearing the fixed sprocket 50. A chain 52 connects the sprockets 50 and 5I With this construction, the sprocket 5| will be swung circularly about the axis of the fixed sprocket 50 as the can support la is moved bodily in the circular path B which has its center in the axis of the fixed stud 40.

On such rotation of the support Illa, the fixed sprocket 50 and chain 52 effect corresponding but reverse rotation of the sprocket 5I which is fixed to the stud 30 and its rotatable can support Illa. The can C is thus rotated backward at the same angular rate that it would otherwise be rotated forward if its support Illa was fixed eccentrically to the gear 33.

Consequently, the cam C maintains xed orientation with respect to the base of the coiler, and no additional twist is imparted to the sliver by the can motion as the sliver is coiled and deposited in the can. The orientation of the can is indicated by the arrow D on the can support Illa (Fig. 2), which arrow points constantly in the same direction.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what we claim is:

1. In a textile machine having a rotated sliver-delivering device, in combination, a fixed frame member, a rotatable support for a can to receive the sliver, a pivot for said support, means to move said pivot bodily in a circular path, a sprocket fixed with respect to said frame member and concentric with said circular path, a second and equal sprocket secured to said rotatable support and concentric therewith, .and clearing said first sprocket, and a sprocket chain rotatably connecting said two sprockets, whereby said support and can are reversely rotated with respect to the direction of circular movement of said pivot and at equal angular speed, so that the orientation of said can with respect to said xed frame member is maintained unchanged at all times.

2. The combination in a textile machine as set forth in claim 1, in which the pivot for the can support is mounted eccentrically in a rotated member, and in which means is provided to rotate said member continuously.
